The purpose of this study is to analyze the characteristics of the New-Hanbok styling of online shopping mall, and to also suggest a solution to the problems of the New-Hanbok styling and develop a progressive plan. The research method was to search six keywords related to 'Hanbok' in the search portal 'Naver' and select 14 Hanbok brand companies. A total of 412 pictures of products for the model used on main screen were analyzed among 14 companies. The results of analyzing the New-Hanbok styling are as follows. First, the New-Hanbok styling showed the unstructured characteristics like unconventional arrangement after getting out of the fixed form of traditional Hanbok styling elements. Secondly, diverse images were represented as the hairstyle and makeup were highlighted as the elements of New-Hanbok styling. Thirdly, the new, fresh, trendy, and fashionable New-Hanbok styling was shown through the mix-and-match of traditional Korean-style accessories and fashion jewelries. However, regarding the New-Hanbok styling shown in online shopping mall, the overlapped items were especially found while the difference in material, pattern, and color required to overcome this problem was insufficient. It was lacking in the styling consistency for the establishment brand image while the awareness of the importance of accessory styling was insufficient. The brand competitiveness of the New-Hanbok could be secured by raising awareness on differentiation, consistency, and importance through the styling elements such as item composition, material, pattern, color, hairstyle, makeup, and accessory of brand.

Objectives: This study aimed to develop evaluation criteria for the elementary-school-based health promotion program using the RE-AIM framework and to examine their feasibility. Methods: Previous evaluation studies on health interventions for elementary-school students using the RE-AIM framework were reviewed systematically to identify appropriate evaluation criteria. A diet and physical activity intervention based on the transtheoretical model was implemented in a pilot study using the "Happy Me" application. The feasibility of using the RE-AIM framework to evaluate it was examined. Results: The review yielded the following evaluation criteria: "reach," the ratio of participants out of the total target population; "efficacy/effectiveness," the difference in outcomes between the intervention and control groups, or between a pre- and post-test; "adoption," the rate of use of the program and participation in the next stage of the program; "implementation," the progress on the program components; "maintenance," the participants' and teachers' intention to continue using the program. The pilot study reached 76.6% of the targeted population. The intake of sugar-sweetened beverages decreased (P < 0.0001), and the duration of walking increased (P < 0.0001). Other indicators could not be evaluated; therefore, potential indicators were suggested. Conclusions: This study produced feasible evaluation criteria for elementary-school-based health promotion using the RE-AIM framework. Nevertheless, the feasibility needs to be validated with a broader range of studies and long-term interventions.

Purpose: This study sought to identify the levels of coronavirus disease 2019 (COVID-19) knowledge, anxiety, nursing professionalism, and clinical practicum stress, and the factors influencing this stress in nursing students. Methods: A cross-sectional and descriptive study was conducted with the participation of 140 junior and senior nursing students recruited from three nursing colleges in Busan and Gyeongsangnam-do. Data analysis was performed using independent t-tests, Pearson's correlation coefficient, and multiple regression using the SPSS/WIN 26.0 program. Results: The study arrived at a mean score of 63.18±13.89 for clinical practicum stress, which showed a significant difference based on the perceived health status and reasons for admission to nursing school. Anxiety and professionalism exhibited a noteworthy correlation with clinical practicum stress. The significant predictors of clinical practicum stress among nursing students were perceived health status (β=.39, p<.001), anxiety (β=.25, p=.033), and the reasons for admission to nursing school (β=.17, p=.012). The total explanatory power of these variables was 23.0% (F=6.28, p<.001). Conclusion: The results of this study suggest that it is necessary to provide effective education to promote nursing professionalism during a pandemic. It is also necessary to develop and include various programs in the curriculum that strategically intervene to prevent anxiety in pre-service nurses. This would reduce the stress in the clinical practice of nursing students when faced with new infectious diseases in the future.

Structural stability of floating platforms has long since been a crucial issue in the field of marine engineering. Excessive motions would not only deteriorate the operating conditions but also seriously impact the safety, service life, and production efficiency. In recent decades, several control devices have been proposed to reduce unwanted motions, and an attractive one is the tuned heave plate (THP). However, the THP system may reduce or even lose its effectiveness when it is mistuned due to the shift of dominant wave frequency. In the present study, a novel adaptive tuned heave plate (ATHP) is proposed based on inerter by adjusting its inertance, which allows to overcome the limitation of the conventional THP and realize adaptations to the dominant wave frequencies in real time. Specifically, the analytical model of a representative semisubmersible platform (SSP) equipped with an ATHP is created, and the equations of motion are formulated accordingly. Two optimization strategies (i.e., J₁ and J₂ optimizations) are developed to determine the optimum design parameters of ATHP. The control effectiveness of the optimized ATHP is then examined in the frequency domain by comparing to those without control and controlled by the conventional THP. Moreover, parametric analyses are systematically performed to evaluate the influences of the pre-specified frequency ratio, damping ratio, heave plate sizes, peak periods and wave heights on the performance of ATHP. Furthermore, a Simulink model is also developed to examine the control performance of ATHP in the time domain. It is demonstrated that the proposed ATHP could adaptively adjust the optimum inertance-to-mass ratio by tracking the dominant wave frequencies in real time, and the proposed system shows better control performance than the conventional THP.

Background : This study aimed at identifying the effect of the standardized protocol on lowering the incidence of the ventilator associated pneumonia(VAP). Methods : The standard protocol focusing on decreasing VAP was made and applied at 5 ICUs (Medical ICU, surgical ICU, Respiratory ICU, Neonatal ICU, Pediatric ICU) in a university affiliated tertiary hospital, from April 1, 2000 to Oct 31, 2000. The protocol involved 3 parts : hand washing, the suctioning method and ventilator circuit management. All the nursing personnel received intensive education which was consisted of lecture, video film and demonstration. 176 nurses reported the performance of handwashing pre and post intervention. And randomly selected 15 nurses were observed by charge nurse and the handwashing practice was analyzed pre and post intervention. The incidence of VAP was compared with the former year incidence. Results : The self reported frequency of hand washing increased. In the direct observation of handwashing, the frequency, time, thoroughness of hand washing during 8 hours day duty was found to be improved. The frequency was increased from 1.1 time to 4.1 times; the time was improved from 1.7 seconds to 5.7 seconds and the thoroughness of the washing practice was from 0.2 times to 3.0 times respectively (p<0.001). The incidence of VAP decreased from at a rate of 15.63 number of case per 1,000 ventilator-day (April 1~August 31, 1999) to 7.23 number of case per 1,000 ventilator-days(April 1~Oct 31, 2000)(P<0.001). Conclusion : We developed the protocols which included hand washing, the suctioning method, and ventilator circuit management. Through the implementation of the protocol, the performance of hand washing improved and the VAP incidence rate in ICU was decreased.

The maternal and child health is a basis of national health, and indicates the level of social welfare and health of the country, because it is related with community welfare status, general cultural conditions, and medical and health sciences. This is a study carried out to identify the present practices of maternal and child health care programs implemented by the private clinics located in Guns(counties ; rural area) in Kyungsangnam Province and to propose alternatives to improve their current programs through a self-administrative questionnaire. The subjects were 90 private physicians who operated their own clinics since 1990 and were general practitioners, Obstertrician/Gynecologists or pediatricians: This survey was conducted by mail from 15 January to 25 February 1992. The response rate was 94.4 percent. 1) The major manpower for MCH programs of the studied clinics was physicians and nurseaids. 70.3% of physicians were general practitioners, 81.1% of nursing manpower were nurseaids. 31.1% of the studied clinics employed lab-technicians. 89.2% of them had MCH room whatever the size and the setting, and 84.4% of Ob/Gyn clinics installed laboratory equipments. 2) 55.4% and 63.5% of the studied clinics provided 151 or above consulting services and curative services of MCH per physician a month respectively and 33.8% and 25.7% of them provided 10 or less consulting services and curative services per physician a month. 91.9% of lab-technicians had 10 or less laboratory tests per technician a month. 3) There was a difference between Ob/Gyn and pediatric clinics in terms of services delivered : for example, 80% of Ob/Gyn clinics provided pre- and post- natal care services, while 84.6% of pediatric clinics provided vaccinations for children. It was also found that only a few of general practitioners involved pre-and post- natal care services. 4) There were no clinics which had opened regular health education session but 24.3% of them had opened the sessions irregularly. Ob/Gyn clinics put emphasis on maternity and pediatric clinics did on child health, but general practitioners touched with both maternal and child health. 21.6% of the studied clinics had some kind of educational materials for MCH programs. Most of the materials were pamphlets or small booklets. 5) Proteinuria/glucosuria, blood pressure and blood type were tested in 48.6~69% of the studied clinics ; tests for blood sugar and hepatitis B were provided in 39.2~41.9% of them, most of them were done in Ob/Gyn clinics. 6) 41.9% of physicians, 29.7% of nurses and 45.9% of nurses-aids wanted to receive on-job-training for MCH programs.
